Abstract
The invention discloses an automatic weighing device of a neonate warm box, which comprises a weighing platform. The weighing platform is located in the warm box, the lower portion of the weighing platform is provided with a weight sensor, the weight sensor is connected with an analog/digital convert, the analog/digital convert is connected with a microprocessor, and the microprocessor is connected with an electronic touch panel. The automatic weighing device of the neonate warm box is reasonable in structure and safe and convenient to use. 24-bit analog to digital (A/D) signals are sent to the microprocessor, the weight of a patient child is displayed on the electronic touch panel after processing, and the weight of the patient child every day can be automatically stored for future review. A displaying portion and a key portion are integrated, the colorful electronic touch panel is adopted, and all status information of a system can be displayed in one time, thereby facilitating clinical reference of medical workers.
Description
Technical field
The present invention relates to the warm automatic weighing apparatus of case of a kind of neonate.
Background technology
In newborn care work, premature especially, body weight is one of important indicator of the reflection infant state of an illness and as the foundation of dosage.As judge infant PD situation; Measure unbalanced patient for discrepancy, can judge edematous condition; For the diarrhoea patient, can observe and have or not dehydration; And premature's medication is strict with body weight accurate Calculation dosage, and to reach optimum curative effect, minimum paying acts on.Therefore premature's body weight monitoring treats, judges that for the direct clinical medication PD situation is significant.At present, in clinical newborn care, every day, body weight was monitored one of routine care as the premature, for common premature; Use baby's electronic scales get final product, but for the critical premature of the state of an illness, especially put warm case, the infant of use lung ventilator; Weigh every day as using the particularly inconvenience of conventional method, need many people's operations, and can be because of moving infant; Influence the infant state of an illness, even cause the infant lung ventilator to take off pipe, again intubate; It is painful to increase infant, even jeopardizes infant life, increases nursing work load and nursing risk greatly.
Summary of the invention
The object of the present invention is to provide neonate a kind of rational in infrastructure, easy to use, safe to warm up the automatic weighing apparatus of case.
Technical solution of the present invention is:
A kind of neonate warms up the automatic weighing apparatus of case, it is characterized in that: comprise weighing unit, weighing unit is arranged in warm case; The weighing unit bottom is provided with weight sensor; Weight sensor is connected with A/D converter, and A/D converter is connected with microprocessor, and microprocessor is connected with the electronic touch screen.
Sensor adopts the beam type LOAD CELLS, and A/D converter is high precision 24 bits serial A/D converter, and the A/D converter chip internal has an extremely low noise chopper-stabilized instrumentation amplifier, and its gain may be selected to be 2n, n=0～6; The inner △ one ∑ modulator that also has one 4 rank of A/D converter is followed a digital filter thereafter, and 10 kinds of alternative output word speed are provided.
The present invention is rational in infrastructure, and is easy to use, safe; 24 A/D signal is delivered to microprocessor, on touch screen, shows the infant body weight after treatment, and can body weight every day of infant be stored the usefulness for review from now on automatically.Show and keyboard portion unites two into one and adopts the color electric touch-screen, can all status informations of display system, make things convenient for the clinical reference of medical personnel.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
A kind of neonate warms up the automatic weighing apparatus of case; Comprise the weighing unit 1 that infant 7 is weighed; Weighing unit is arranged in warm case 2, and the weighing unit bottom is provided with weight sensor 3, and weight sensor is connected with A/D converter 4; A/D converter is connected with microprocessor 5, and microprocessor is connected with electronic touch screen 6.
Sensor adopts the beam type LOAD CELLS, and A/D converter is high precision 24 bits serial A/D converter, and it is the △-∑ A/D converter of high integration, owing to used charge balance technique, its performance can reach 24.Very be fit to measure the list/bipolarity small-signal of applications such as weighing instrument, process control, science and medical treatment; The A/D converter chip internal has an extremely low noise chopper-stabilized instrumentation amplifier, and its gain may be selected to be 2n, and n=0～6 have enlarged the signal input range, allows the input of small-signal, has improved the dynamic perfromance of system.Its common-mode rejection ratio representative value at 50 Hz can reach 120 dB, and this is very favourable to from high common mode voltage, detecting faint differential voltage signal.The inner △ one ∑ modulator that also has one 4 rank of A/D converter is followed a digital filter thereafter, and 10 kinds of alternative output word speed are provided.Utilize inner calibration system (comprising self calibration and system calibration), ADC zeros of transfer functions and gain slope can be set, thereby eliminate the imbalance and the gain error of system channel.
